Cloyster

Cloyster is one of the most offensively oriented entry hazard controllers in the tier and requires prediction and very aggressive play in order to keep the field free of entry hazards. Cloyster also has access to Spikes and the coveted Toxic Spikes to further support the team, and it uses its great offensive typing, powerful STAB move in Icicle Spear, and excellent boosting move in Shell Smash to pressure opposing Defoggers and entry hazard setters alike. Cloyster can beat most opposing entry hazard leads, such as Deoxys-S and Deoxys-A, or can outspeed and wear down bulky entry hazard setters such as Primal Groudon and Dialga for the next Pokemon to take them out. However, Cloyster dislikes bulky Defoggers that can shrug off its STAB move, such as Arceus and Scizor, and requires a bit of team support to make the most of its niche. Overall, Cloyster is an excellent utility Pokemon that, although it requires very aggressive play, can control entry hazards in your favor and set up your threatening sweepers to put in lots of work.
